English Network/Internet

Hello,
i have opensuse 13.2 and I’m not able to discover bluetooth device (even if there are, I have verified with other devices)

This is my situation:

linux-mixt:/home/sirley # dmesg |grep -i Bluetooth

All seems OK but the hcitool scan look like this:

linux-mixt:/home/sirley # hcitool scan
Scanning ...

End after 10 seconds ends with no results.

In YAST I can see the bleutooth device and the model is Realtek Bluetooth Radio (but I don’t know exactly which chipset it is, how can I check this?).
Searching in google I have found Ubuntu users suggesting for installing the pakages
rtlwifi-new-dkms linux-firmware rtl8723au-bt-dkms

But I don’t know where to find these pakages and if they are really realted to my chipset…

Do you have any idea?

Thanks in advance

Hello,
I have solved my issue.
Here the solution:

first of all I have installed this driver https://github.com/lwfinger/rtlwifi_new

because my bluetooth is integrated in the WiFi realtek RTL8723BE.
After that I have installed this bluetooth driver:

https://github.com/troy-tan/driver_store/tree/master/bluetooth/8723BE

Reboot.

Fixed :slight_smile:

Thanks.

Giorgio

I have exactly the same problem.
Can anyone explain - please:
How do you install a driver from such a rar-file?
